This invention relates to a safety razor which is constructed and arranged to permit of limited flexing of the kblade intermediate the ends thereof.

The invention comprehends aisafety razor in- I cluding aflexible blade and a blade holder have.

ing clamping means for holding the blade against movement at the ends thereof but which per.- mits of-limited flexing of the blade toward' and away fromthe guard edge thereof intermediate the ends of the blade.

Another object of the invention is to :pro-` vide a blade holder having blade clamping elements which are movable into engagement over thel ends ofthe blade for releasably'securingthe-v blade on the holder and which includes a clamping element adapted to be moved into overlying relation with the blade substantiallycentrally thereof for limiting the outward flexing of vthe blade.v r z lStill another object of the'invention is to provide a vrazor blade including a holder having a guard edge disposed in spaced relation from the `cutting edgeA of the blade and with clamp'- ing means fcrreleasably securing the blade in position thereon to permit of limited flexing ofthe cutting edge portion of the blade toward and away from the guard edge.

With the foregoing and'other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiments of the invention are illustrated.

Referring to the drawings `bycharacters of reference and-more particularlyto theform of the invention illustrated in Figs; lzto 4 inclusive thereof, the rrazor includes 'a' .blade holderzl.

having one or more longitudinally extending guard edges Il, two being shownin-,the embodiment illustrated for accommodatingr al double-edge blade Bhaving oppositely disposed longitudinally extending cutting edges l2. blade is formed witha longitudinally extending slot I3 located centrally between the cutting notches t4 at the edges.v and'is provided with cornerstthereof.; s ,f I Y The blade Aholder I0 is ,formedwith a rectangular recess l5 ,extending 'longitudinally between the longitudinal edgefportions I6 thereof in which is fitted aplate I1 secured thereto by rivets I8 at the opposite'ends and havingdepending transversely extending flanges 20 `at its ends vwhich provide a transversely extendingv recess 2l-in the underside of said platebetween the flangesA and between the Vplate l1. vand the bottom ofthe recess Al5. The plate I1 is formed withraised corner portions 22.while` thelongitudinal edge portions i6 of the'holder are formedwith raised ends 23 which raisedcornerportions and ends constitute supportingsurfaces atfthe cornersV ofv the holder for :supporting the Vblade 2B in position thereon with the upper surfaces of the longitudinally extending edge portions i6 between the raised ends 23 being located in spaced relation below the cutting edges 'l2 of the blade and extending outwardly beyond the. said cutting edges.

VThe homer 10 is rigidly amxd 6o a tubular handle 24 in which a shaft'Zl'v is mounted for swivel turning,movementwith the-.lower end thereof secured to'amanipulatingknob 26 and the upper -end-of the' shaftsecured to a cam disk opposite 4side Walls ofthe recess .l5 andare formed'with outwardly directed'terminals 32 4at the outer ends thereof which protrude through c recesses 33 in the raised corner portions 22 and have inwardly directed free upper ends '34- adapted-'to be moved into voverlying relation with The:V

the notched corners of the blade for securing the blade in position upon the raised corner portions 22 and the raised ends 23 of the longitudinally extending edge portions I5.

In order to impart longitudinal reciprocatory movement to the plates 3D and 3l for moving the free ends 34 of the terminals 32 into and out of overlying relation with the blade, the cam disk 21 is formed with oppositely disposed arcuate slots 35 .opening ithrough the upper face thereof which are engaged by pins 36 depending from the plates 39 and 3l. The arcuate slots 35 are formed eccentric to the axis of the shaft 25 ing 54 in the upper end thereof in which is threadwhereby turning of the shaft by 'manipulatingthe knob 26 will rotate the cam disk 21 to .pro-v 30 and 3l outwardly when the knob 26 is turned in one direction so as to move the free upperl ends 34 of the terminals -32 out of overlying engagement with `the blade and'when 'the knob 26 is turned in vthe opposite direction'to thereby move the plates '30 .and 3l inwardly so as to .move the ends 34 of the terminals 32 into overlying clamping engagement with the blade.

In order to limit the outward flexing of the blade B without interfering with the .inward flexing thereof towards. the longitudinal edge portions I5 intermediate the ends of the blade, the cam disk 21 is formed with .a central stud 31 which protrudes outwardly through a 'central opening 38 vin the plate Hand is .provided with an elongated head 39 which is rotatable from an aligned position with the slot .13 in Vithel blade to a transversely extending position in' overlying relation with .the vblade to thereby dispose the outer ends of the head 39 adjacent the cutting edges thereof. ,It will be. understood that When the head 39-s in the 'aligned position With.

the .slot I3 in thel blade, the free ends v311 of the terminals 32 will be moved outwardly from overlying relation With the'blade so that the blade can be removed "from the holder 'and when .the head 39 is moved t-o a position transversely :of the blade, the free ends '34 of the terminals 32 are moved inwardly into overlying relation with the blade for securing the blade on the holder.

The blade yholder lll is provided with a rib dil extending `longitudinally of and projecting upwardly from the upper surface of the vplate l1 and which is cut away 4centrally thereof to ireceive the elongatedhead 39 in alignment with the end portions of the rib and which lend portions of the rib .project through the slot I3 in the plate for positioning the blade upon the blade holder.

In Aorder vto tension the shaft 25 against too free turning movement a spring wash-er 42 is located in a recess 43 at the lower end of the handle 24 which frictionally engages the inner endofitheknob26-` v In the form of the invention. illustrated lin Figs. 5 to 1l)V inclusive of thetirawings, the razor includes V'a blade holder '45 having one or more longitudinally extending .guard edges 158, two being shown inthe embodiment'illustrated for accommodating a double-'edge blade C similarto Athe blade B .in the previous .form of the invention and .having oppositely disposed Alongitudinally extending cutting'edges 41. The vblade holder S5 is vformed with raised ends 43 at the opposite ends of the longitudinally extending edge portions 49 located on opposite sides of the holder for supporting the blade Ain position on said raised ends 48 with the longitudinally extending edge portions 49 between the raised ends 48 being lo- 'edly received a threaded shank 55 depending 'from the lower edge of a vertically disposed bar 56 ,Y extending longitudinally of the holder and whichis of a length to engage through the longitudinally extending slot 51 in the blade C for disposing the blade in position on the holder.

By turning the manipulating knob l52 the bar 56 is movable from a retracted position in which the lower portion thereof is Vdisposedin a longitudinally .extending slot 59 .in the holder with the upper .portion thereof projecting therethrough vto a projected position in which the bar is disposed above the holder. Arranged on the holder for movement with the `bar 5S are oppositely disposed vclamping elements 60 which are 'swingable from an overlying clampingrelaton with the blade to an upstanding released position in which the blade may be removed from the holder.

The clamping elements 65 each include a dat inner portion .Si and right angularly related ends 62 which extend .laterally outward therefrom and .are formed lwith depending projections 63 having inwardly oiiset lugs 54 at the inner ends thereof. yThe said projections have reciprocatory movement in notches 65 'at the corners ofthe holder with their lower ends pivoted on pivot pins 65 to varms 61 extending outwardly from the ends of the bar 56. The holder is formed with inclined walls 68 on one sideof the notches 55 which are engaged by the lugs 64 for imparting turning movement to 'theclamping elements 50 to thereby swing the same :into overlying clamping relation with the blade when the manipulating knob 52 is turned in one direction and to cam the lower end o'f the projections 63 inwardly so as to swing the lclamping elements on the pivot pins 56 into an opstanding released position when the manipulating knob is turned in the opposite direction to elevate the clamping elements 50.

The clamping elements 60 are also formed with medial tongues 69 extending laterally outward from the inner portion SI thereof centrally between the lends 62 with the free ends of the tongues adapted to be disposed adjacent the cutting edges of the blade when the clamping elements are arranged'in overlying clamping relation with the blade. The tongues 59 function to limit the outward flexing of the blade intermediate the ends thereof but permit flexing thereof between the longitudinally extending edge portions 119 While the ends 62 of the clamping elements engage against the blade at the ends thereof and clamp the same against the raised ends 48.

What is claimed is:

l. In a safety razor, a blade holder having guard edge portions at the opposite sides thereof and raised areas at the opposite ends of said guard edge portions for supporting the blade at the four corners thereof with the blade disposed flatly upon said raised areas with the cutting edges thereof spaced above the guard edge portions between said raised areas, blade clamping means movable into overlying relation with the blade at the ends thereof for releasably securing the blade in flat unflexed condition on the holder, a medial clamping element movable with said means into overlying relation with the blade medially of the ends thereof for preventing the outward ilexing of the blade and permitting of the inward flexing of said blade between said raised areas, a handle, and a manipulating knob carried by said handle for manually moving said blade clamping means and said clamping element into and out of overlying engagement with the blade.

2. In a safety razor, a blade holder having a top Wall provided with raised portions at the corners thereof with the upper surfaces of said raised portions being disposed in alignment for supporting the blade at the corners thereof in at elevated relation above the intermediate edge portions of the top wall, clamping means movable into overlying relation with the blade above said raised portions and medially of the ends thereof for releasably securing the blade on said top wall and for preventing the outward flexing of the blade between said raised portions and permitting of the inward flexing of said blade due to the flat unflexed condition thereof.
